在C#开发中如何使用Client Object Model客户端代码获得SharePoint 网站、列表的权限情况

     //如果你想获得SITE的权限列表，应该这样写
            //string ObjectType = "Site", ObjectTitle = "网站名称", SiteUrl = "网站的URL";
            string ObjectType = "List", ObjectTitle = "文档", SiteUrl = "http://sp2013";

            ClientContext clientContext = new ClientContext(SiteUrl);
            clientContext.Credentials = new NetworkCredential("administrator", "密码");
            List selectedList = null;
            Web selectedWeb = null;
            Console.WriteLine("Object:" + ObjectType + " Name:" + ObjectTitle + " URL:" + SiteUrl);
            try
            {
                if (ObjectType != "Site")
                {
                    selectedList = clientContext.Web.Lists.GetByTitle(ObjectTitle);
                    clientContext.Load(selectedList);  
                    
                }
                else
                {
                    selectedWeb = clientContext.Web;                
                    clientContext.Load(selectedWeb);

                }

                clientContext.ExecuteQuery();
            }
            catch (Exception  wex)
            {
                Console.WriteLine(wex.Message);
                Console.ReadLine();
                return;
            }
            RoleAssignmentCollection ras = null;
            if (ObjectType != "Site")
            {
                ras = selectedList.RoleAssignments;
                clientContext.Load(ras);
            }
            else
            {
                ras = selectedWeb.RoleAssignments;
                clientContext.Load(ras);
            }
            
            clientContext.ExecuteQuery();
            Console.WriteLine("It has " + ras.Count + " role assignments");
            foreach (var ra in ras)
            {
                clientContext.Load(ra.RoleDefinitionBindings);
                clientContext.Load(ra.Member);
                clientContext.ExecuteQuery();
                foreach (var definition in ra.RoleDefinitionBindings)
                {
                    clientContext.Load(definition, d => d.Name);
                    clientContext.ExecuteQuery();
                    //C#在输入中英文混合字符时，对齐会不正常，这个语句主要是给用户名添加空格的
                    string tmpname = ra.Member.Title.Trim() + new string(‘ ‘, 30 - Encoding.Default.GetByteCount(ra.Member.Title.Trim()));
                    Console.WriteLine("{0,-20}{1}{2,-15}", ra.Member.PrincipalType.ToString().Trim(), tmpname, definition.Name);
                }
            }
         
            Console.ReadLine();

clientContext.Load(变量名或是对象,linq表达式);
clientContext.ExecuteQuery();
